PROBLEM TO BE SOLVED: To provide an excellent production method suitable for producing reduced coenzyme Q<SB>10</SB>crystals in an industrial scale. SOLUTION: Reduced coenzyme Q<SB>10</SB>crystals excellent in slurry properties or crystal properties can be produced by the production method of the reduced coenzyme Q<SB>10</SB>crystals in which reduced coenzyme Q<SB>10</SB>is crystallized in a solution of alcohols and/or ketones. An isolation process including separation of crystals or the whole process including the isolation process can be at most shortened and simplified, thus highly pure reduced coenzyme Q<SB>10</SB>can be obtained in a high yield.
